Q: I have about £450 GBP to spend on miners ..... was going to get 2x S3, looks like I can get a couple for under £400 ...... would that be my best option? I'm fortunate in that I can run them for 12 hours a day on free electric (work), so power consumption cost are not an issue .....

Currenty I use this strategy.2/3 of Hashing power to Slush > electricy (yes in holland energy is expensive..)

1/3 for benefits/investments. Wanted to try out CKpool/Eligius with 1/3 of HP, but i don't know how steady they with payout. Meaning.. the payout system.24TH @ slush gives me around 0.073 per block. Anyone experience with CKpool/Eligius?

In cgminer it says 98Gh/s - 103Gh/s. However, the slush's pool site I have now been able to over 80 Gh/s. Is it just me, or just something on the site?

For example, right now I see "78.544 Ghash/s"

I think you may assume that the figure in CGminer is correct. The figure on Slush's site is back-calculated from results submitted (the site has no way of knowing your true hash rate). What does CGminer say your difficulty per submitted share is? You might want to try setting that slightly higher on the web site, e.g. if your difficulty is running at 48, try setting it to 56 and see what happens. My own S3+ rigs are set to run at 256 minimum difficulty, which gives me better results than letting the pool set it dynamically.

Thanks for the tip. Getting better results on my 2 S3+ now I've set the difficulty to a min of 256

Thanks for the help indeed. So right now in cgminer I see it set as diff 60, and it is still getting the same average, when it should be at least 100Gh/s. My last question regarding this is how do I set the difficulty exactly? Out of all of my miners, I never had to look into changing that.

For that much you could buy a Jackson (Spondoolies SP-20) that has more than double the has rate of 2 x S3's.

Now about the pool. Who has been talking about the pool online?The first rule of Slush pool is you don't talk about slush pool;the second rule of Slush pool is you don't talk about Slush pool!

2.5 PH just jumped into the pool (that is in addition to the 750 TH that has been jumping in and out over the past two weeks) and cut my share of each block by nearly 20%.

For the last block I got a much lower payout than usual. For block #23112 I had 4455042 out of 63594928318 which computes to a reward of 0.00176398 BTC and that is what I was paid. For block 23112 I had 4389489 out of 85565358653 which computes to a reward of 0.001285 BTC. My BTC reward is only shown as 0.00005305. That's like 4% of what it should be. What's up with that?

Pool performance jumped - somebody redirected big power to slush, possible some company tested something.Just now they dropped out, so, after that back to "normal" payout...Slush luck is dropping now, so faster to go trough blocks is not bad thing.

Did you look at the data? Pool performance didn't jump. I received 25 times less BTC than I should have.

I usually receive .0016-.0018 BTC per payout. .00005 is a lot less than that. I got screwed for some reason.

You submitted less shares in the 11:54 round than in the 8:53 round. Likely your miner went offline or you took it offline shortly before the 9 hour mark of the block, and because of the way the Slush scoring algorithm works you received a much lower payout.

Yeah I took it offline for a few hours but I didn't know I would receive 96% less payout otherwise I would have taken it offline for the entire 12 hours. How does the algorithm work?

Need to wait for a block to be found then take it offline. If taken offline during a round you lose substantial part of reward.
